Title: Adjustable propulsion nozzles
Inventor: HALL JOHN WALLACE
IPC: F02K1/08
Filed: 1957-07-17
Abstract: 851,225. Jet-propulsion nozzles. DE HAVILLAND ENGINE CO. Ltd. July 17, 1958 [July 17, 1957], No. 22673/58. Divided out of 851,224. Class 110 (3). A jet-propulsion nozzle comprising an upstream generally convergent tubular nozzle portion, a downstream generally divergent tubular nozzle portion which is incapable of axial movement relative to the upstream nozzle portion, a throat portion between the nozzle portions, a ring of petals for varying the cross-section of the throat portion and means for operating the petals, has a cooling air duct which surrounds the convergent nozzle portion and lies between the convergent portion and the nozzle-operating mechanism and which supplies a continuous flow of control gas into the downstream divergent portion from behind the petals. Jet-propulsion nozzle, Fig. 2, comprises a fixed convergent tubular nozzle portion 4, a series of circumferentially-spaced adjustable petals 6 and a fixed divergent rearwardly extending portion 5 leading to an exhaust orifice 8. The petals 6 are operated by mechanism 9 housed in the nacelle 10. When the petals are in the fully closed position shown in broken lines at 12, the nozzle acts as a wholly convergent nozzle. To avoid high drag losses in this position of the petals due to airflow over the engine casing 10 entering the region between the wall 5 of the fixed divergent nozzle and the propulsive jet, a controlled airflow 14 is fed from behind the petals to occupy the region. An annular control air duct 15 formed between a wall 16 forming the inner wall of a chamber 17 housing the operating mechanism 9 and the convergent wall 4 leads air from any suitable source, such as ram air from an auxiliary air intake or from the region between the aircraft and engine intakes to the region. The upstream end 18 of each petal co-operates with a sealing member 19 to ensure that the gas leaves on the rearward side of the petals. When the petals are in the fully divergent position they abut against a corrugated spacer strip 24 so that the control gas may be used to cool the petals and the wall of the nozzle. A further supply of cooling gas is supplied to the chamber 17 and is discharged through the nozzle 26. A heat shield 27 is provided to protect the wall 4. The duct 28 receives gas from the turbine exhaust. Heatresistant lagging 30 is also provided. In a modification, Fig. 3 (not shown), the petaloperating mechanism is of the type described in Specification 851,224.
